idles mush too fast prob. about 1500-----------2000rpm I dont think the problem is with the mixture,
the top trottle bar lever contacts the lever from the distrubtor which is hitting the metal framing and not letting the throttle plates close

can the throttle lever stop on each carb. be adjusted on the throttle shafts?

could someone have assemble this wrong,, MOTOR IS NEW TO ME

Should be an Idle screw right there somewhere, turn it out, but you might have to adjust the cable also, to put pressure on the shaft to hold it closed.
